The messages can to have different types.
$queue->producer()->send('Hello', 2); $queue->consumer()->tryReceive() === NULL // non blocking read $queue->consumer()->receive(2)->message === 'Hello'
Or read all types
$queue->producer()->send('Hello', 2); $queue->consumer()->receive(Queue\Config::TYPE_ALL)->message === 'Hello'
